Jared Allen fine for Sunday ... and Ponder engaged?

Vikings defensive end Jared Allen developed some minor lower back spasms following Sunday's 23-14 loss in Green Bay. But an MRI taken Monday on Allen's back revealed no structural damage, according to an NFL source.

The Vikings were never worried about the severity of Allen's injury but now have peace of mind and expect him to be fine for Sunday's game against Chicago.

Head coach Leslie Frazier was asked about Allen's shoulder injury after Sunday's loss but didn't want to talk about it.

"I don't really want to discuss his injuries. Jared's played every game this season. Like most guys, especially this time of year, he's playing through something. Very few guys who are playing this time of the year and that have played as many snaps as he's played are 100 percent, even when they're out there playing. So I really don't want to talk about anybody's injuries. All our guys are playing."
